Paper Abstract
In this work a magnetic field sensor based on an FBG coated with a thin film of Terfenol-D is presented. The sensor was
tested with two optical interrogation systems: one, a scanning laser system with a 1 pm resolution, and the other a
differential white light interferometer (WLI). The results obtained in the magnetic field range of 20 mT to 100 mT, show
the possibility of increasing the magnetic field measurement resolution, with temperature fluctuations invariance, by a
factor of 4.5 when using the WLI system.
